Compress images for book publishing

Book files choke on oversized images: PDF proofs get rejected, ebooks fail to upload, print files crawl through email. Skwish compresses JPG, PNG, and WebP images locally in your browser — no uploads — so your manuscript, interior art, and cover files stay under publisher limits.
